Bar plot of categorical data

Hi!

I have a small column vector (46x1). Each row has a number (0-7), where each number encodes a specific electrode location. I want to create a bar plot essentially with the relative (or absolute) frequency of each number. Therefore something like this:

If if use the histogram() function, then it only plots a line connecting the dots

And if I use bar() function, then it plots each row individually.

Can you please help? thank you!

histogram seems to work fine:

data = randi([0,7],46,1);

histogram(data)

Maybe you have another function called histogram that's being run instead. Do

which histogram -all

to see which histogram functions you have, and if there are any besides the built-in, rename them to something else.
